FASTENER.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed. May 29, 1906. Serial No. 319,270:

To all whom fit may concern:

Be it known that I, ALFRED M. CLARK, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to improvements in fasteners.

It relates particularly to an improved fastrner for tapes, bands, straps, cords, or the i ze.

The objects of this invention are, first, to provide an improved fastener for tapes, etc., which is very secure and at the same time is very easy to manipulate. Second, to provide an improved fastener which enables a tape or the like to be drawn into position and secured in any position within the scope of the same. Third, to provide an improved fastener which may be formed of a single piece of material. Fourth, to provide an improved fastener for tapes and the like, which has no movableor adjustable parts. Fifth, to provide an improved fastener which is very economical to produce, is very compact, and may be made of light material and still be very strong.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined andpointed out in the claims.

A structure embodying` the features of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which- Figure l is a detail plan of a structure em.- bodying the features of my invention. Fig. 2 is a detail edge view of the structure shown in Fig. l. Fig. 3 is an inverted plan of a structure embodying the featuresof my invention. Fig. 4 is an enlarged detail longitudinal section taken on a line corresponding to line Lf 4 of Figs. 5 and 6. Fig. 5 is a cross-section taken on a line corresponding to line 5 5 of Fig. 4, showing the relation of the parts. Fig. 6 is a detail cross-section taken on a line corresponding to line 6 6 of Fig. 4, showing the relation of the parts. Fig. 7 is a plan of a blank from which my improved fastener is formed, the same being shown slitted ready for the parts to be struck up. Fig. 8 is a detail -cross-section of a modified construction.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawing, my improved fastener consists of a body portion A which is preferably secured to one end of the band or tape B by the lugs or fingers o which are struck up therefrom and folded down or clamped upon the tape, as clearly appears in Fig. 3. A pair of fastening members e e" are arranged transversely on the body, one behind the other, the fastening members being somewhat hook-like in form. These fastening members are preferably struck up from the piece of material from which the body is formed, and folded over the same, as clearly appears from Figs. 4, 5, and 6 of the drawing. The member a is the forward member and is provided with a forwardly projecting retaining lug c at its outer edge. The member a is arranged so that the strap or band can be readily slipped under the same, as is illustrated in Fig. 4. The member a" is far enough from the body A so that theband ortape to be fastened may be slipped under it when doubled. The body A is preferably provided with a projecting guide piece A adapted to guide the tape or band into the engaging members. The body A is also preferably provided with a rearwardly pro jecting finger piece A by which it may be held when securing the tape. ln engaging the tape with the fastener it is first slipped under both the engaging members and the end is then brought back over the forward member and under the rear member. This holds the tape so that the tendency is when there is a pull upon the same, for the forward member to clutch the tape. It is preferred that the fastening member shall be so located in reference to the body that when the tapes are slipped under the same it may be done easily and still be snug enough to prevent accidental disengagement. When it is desired to unfasten the band it is only necessary to draw the same from under the fastener member am and bring it forwardly to disengage it from the member a when it will slip readily from the fastener.

The forwardly projecting lug a on the forward fastener member is mainly of advantage in adjusting the fastener as it aids in preventing the accidental slipping of the tape from the fastener while being adjusted.

There the device is to be used with very wide bands, I preferably form the structure as is illustrated in the modification shown in Fig. S. Instead of the lug a at the outer end of the member a, I provide a tooth or lug, as am, the advantage being that the wide tape orband is thus effectively held while it is being slipped under the fastener member am. l

My improved fastener is particularly ada p ted for use as a fastener for cords or bands for typesetters use in tying forms, etc., for stationery bands, for binding packages, or the like. It is also of advantage for use as a fastener for packagesinstead of a cord. The fastener may be quickly secured and as quickly released. It may be attached or detached indefinitely. It has `no movable member, so that the fastening members are objects.

always in proper position, and it is not likely to injure the band or tape. It is evident that the same may be drawnvery tightly and secured in position this can be done without danger of its loosening during the engagement of the band with the fastener. Another advantage is that it is very compact and lies Iflat against the package, with no projecting portions which are likely to engage exterior While my improved fastener is p articularly adapted for use as a fastener for flat tapes or bands, it is also desirable for use as a fastener for round cords.

My improved fastener can be conveniently formed in one piece by stamping the same up from a piece of sheet metal, a blank therefor being` illustrated in Fig. 7.

I have illustrated and described my improved fastener in detail in the formv preferred by me on account of its structural simplicity and economy, although I am aware that it may be very considerably varied in structural details within the scope of the ap pended claims without departing from my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. The combination with a band or tape of a fastener formed of a single piece of sheet metal consisting` of a body portion, a transversely arranged hook-like engaging memi ber having a forwardly projecting lug on its forward edge, a transversely arranged hooklike engaging member arranged at the rear thereof, a guide piece projecting from said body below said engaging members, and a projecting finger piece on the opposite side of said body.

2. The combination with a band or tape, of a fastener formed of a single piece of sheet metal consisting of a body portion, a transversely arranged hook-like engaging member having a forwardly projecting lug on its forward edge, a transversely arranged hooklike engaging member arranged at the rear thereof, and a guide piece projecting from said body below said engaging members.

3. The combination with a band or tape, of a fastener formed of a single piece of sheet metal consisting of a body portion, a transversely-arranged hook-like engaging member having a forwardly-projecting lug on'its forward edge and a transversely-arranged hook-like member arranged at the rear thereof, said front engaging member being adapted to receive a single thickness of tape and said rear engaging member being adapted to receive a double thickness of tape,

whereby said tape may be passed under both of said engaging members and turned rearwardly over the front engaging member and again passed under the rear engaging member, as specified.

4. The combination with a band or tape,

of a fastener formed of a single piece of sheet metal consisting of a body portion, a transversely-arranged hook-like engaging member, and a transversely-arranged hook-like member arranged at the rear thereof, said front engaging member being adapted to receive a single thickness of tape and said rear engaging member being adapted to receive a double thickness of tape, whereby said tape may be passed under both of said engaging members and turned rearwardly over the front engaging member' and again passed under the rear engaging member, as specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
